I assume any answers SSHRC has given for waitlisted people (I've copied a reply below that someone posted in the Waitlist thread) would be equally applicable to those who get upgraded. I expect there will be lots of movement over the next few weeks and possibly even months due to people finalizing their plans for the academic year. But, that is just my guess. It wouldn't hurt to email SSHRC to ask, although I'd expect a somewhat vague response.
"Applicants who are advised that their application has been recommended by the committee but not funded are placed on a waiting / recommended list. SSHRC uses these lists, which are committee specific, to offer awards as funds become available. Periodically, supplementary funds may become available as a result of declines of offered awards, interruptions of awards, early termination of previous awards, etc. These factors make it complex to predict when or if a particular candidate is likely to secure funding during this competition cycle. Consequently, while SSHRC offers candidates with their relative score, SSHRC does not offer candidates their committee specific ranking.
